WOODWARD digital input modules are specialized electronic components designed to receive digital signals from various sensors, switches, and other devices within a control system. These modules convert these digital signals into a format that can be understood by a controller, such as a PLC or DCS. They are often used in industrial automation, power generation, and process control applications.

Key Functions

Signal conditioning: Convert various types of digital signals (e.g., voltage, current, frequency) into a standardized format.
Isolation: Provide electrical isolation between the input signal and the module to prevent interference and protect equipment.
Filtering: Filter out noise and other unwanted signals to ensure accurate data acquisition.
Data acquisition: Collect digital data from connected devices and transmit it to a controller.

Product Parameters (Typical)

Number of channels: The number of digital inputs per module.
Input types: Voltage, current, frequency, or pulse.
Input range: The minimum and maximum input values each channel can accept.
Response time: The time it takes for the module to respond to a change in the input signal.
Isolation: The level of electrical isolation between the input and output circuits.
Operating temperature: The range of temperatures at which the module can operate.
Power requirements: The voltage and current required to power the module.

Product Advantages

Versatility: Capable of handling a wide range of digital input signals.
Reliability: Designed for rugged industrial environments.
Compatibility: Compatible with various WOODWARD control systems.
Customization: Can be configured to meet specific application requirements.
Safety: Incorporate safety features to protect equipment and personnel.

Precautions
